Following months of promises and multiple delays, Facebook-owned WhatsApp, which commands more than 800 million active users worldwide, on Tuesday started rolling a voice calling feature in its iPhone application.

WhatsApp Calling is a staggered release and will be rolling out “slowly over the next several weeks,” the company said, meaning it may not be available for you immediately.

In addition to calling other people for free over Wi-Fi networks, regardless of where they may live, the app has gained other enhancements, too, starting with a much welcomed app extension on iPhones running iOS 8. Sadly enough, this update hasn’t brought out support for iOS 8’s Interactive Notifications.

Using WhatsApp’s handy extension, it’s now easy to share links to articles and media from other apps using iOS 8’s multi-purpose Share widget. As the top screenshot shows, I was able to use the extension to send an iDB article URL to Sebastien, right from Safari.

And here’s sharing images to WhatsApp from Apple’s stock Photos app.

As mentioned before, WhatsApp uses Wi-Fi networks for voice calling, so you won’t have to worry about international rate hikes. The app does not support VoIP calling over your cellular data connection as of yet.

Other new features and enhancements in this edition of WhatsApp include a faster way to snap up photos and capture videos in chats, using a quick camera access button.

Moreover, it is at last possible to send multiple videos at once, as well as crop and rotate videos before sending them. Here’s adding multiple videos to a WhatsApp chat, followed by rotating and cropping a single video before sending.

As a bonus, you can now edit your phone contacts who are on WhatsApp right within the app itself (assuming you’ve allowed WhatsApp access to your phone’s contacts), without having to switch to Apple’s stock Contacts app.

WhatsApp 2.12.1 changelog:

WhatsApp Calling: Call your friends and family using WhatsApp for free, even if they’re in another country. WhatsApp calls use your phone’s Internet connection rather than your cellular plan’s voice minutes. Data charges may apply. Note: WhatsApp Calling is rolling out slowly over the next several weeks.

iOS 8 share extension: Share photos, videos, and links right to WhatsApp from other apps.

Quick camera button in chats: Now you can capture photos and videos, or quickly choose a recent camera roll photo or video.

Edit your contacts right from WhatsApp.

Send multiple videos at once and crop and rotate videos before sending them.

Although the groundwork for voice calling was actually laid in WhatsApp months ago, the feature wasn’t functional at the time. On jailbroken devices, a Cydia tweak titled WhatsApp Call Enablersaw to that.
